7 Risk of fatal electrical shock and fire! Mains voltage inside the COFFEE machine . Unplug appliance before cleaning. Never clean wet or immerse plug, cord or appliance in any fluid. Disconnect the mains plug before disassembly the appliance must be free of voltage. This device does not protect against electrical shock due to contact with both cir cuit conductors. Example illustrations of typical devices. Use a GFCI with a trip level of 4 6 mA (USA) resp. a RCD with a trip level of 15 30 mA (Europe). A trip level above 30 mA provides only very limited protection against harm from an electric shock. 1) RCD protected socket outlet 2) Plug in RCD unit 3) GFCI socket 4) Plug in GFCI Danger of burns! Hot parts and water under pressure inside the COFFEE machine (particularly in the thermoblock).
